1. DESCRIPTION

BHL6 is a single skin paraglider with a 8.01 aspect ratio. It’s a crazy idea...! but possible. Because others have done it successfully before. It will not be easy to find the combination of parameters to achieve a high-performance and stable wing, but we will try! In the month of may 2021, we must study what are the best settings...

It is essential to choose the basic parameters correctly to give a good wing solidity!

- planform
- vault
- profile
- relative airfoils washin
- height of lines
- skin tension of the panels
- position of the ABCDE anchors
- diagonal panel system
- line system
- stabilo system
- calage

4. CONSTRUCTION

Currently, there is no prototype in construction. In May 2021, still in the design phase! :)



LAB NOTE: Build a paraglider at home is a very complicated task (even simple skin), and requires many hours of work. Previous experience is required, and very inventive. As always remember that: The free flight implies risks that can only be known and they can be controled with a suitable formation on the part of a recognized school. Not test wings without knowing their functioning. The construction and test of experimental wings without certifying requires deep knowledge of what is being made.
